  • Patent number: 11783179
    Abstract: A method of automatically generating a terminology definition knowledge base (KB) includes mapping each word in a word sequence to a real value dense vector using dense vector representations. The word sequence is then processed using a Convolutional Neural Network (CNN) model to identify whether the word sequence includes a terminology definition and to label the word sequence with a label indicating whether a terminology definition exists within the word sequence. The word sequence is then processed using a Conditional Random Field (CRF) model to identify boundaries of the terminology definition in the word sequence. The terminology definition is then extracted and added to the terminology definition KB.

  • Publication number: 20220072097
    Abstract: Disclosed herein are compositions and methods for treating and preventing neurodegenerative diseases, such as Alzheimer's disease. In some embodiments, the composition comprises a peptide that disrupts the binding between PTP? and APP, preventing ?-amyloidogenic processing of APP without affecting other major substrates of ?- and ?-secretases. Alternatively, in some embodiments, an antibody or a fragment of an antibody against PTP? or APP may be used to disrupt the binding between PTP? and APP. In some embodiments, the composition comprises compounds or enzymes, which restore perineuronal balance of PTP? ligands CS and HS, thereby preventing abnormally increased ?-amyloidogenic processing of APP. Compositions and methods disclosed herein can be used in combination to treat and prevent neurodegenerative diseases.

  • Patent number: 11078337
    Abstract: The present invention is broadly concerned with novel directed self-assembly compositions, processes utilizing those compositions, and the resulting structures that are formed. The composition comprises a block copolymer of polystyrene and a polymethylmethacrylate block with polylactic acid side chains (“PS-b-P(MMA-LA)”). The block copolymer is capable of crosslinking and micro-phase separating into lines and spaces measuring about 10-nm or smaller with sub-20 nm L0 capability. Additionally, PS-b-P(MMA-LA) can be thermally annealed without a top-coat for simpler processing than the prior art. The polylactic acid side chains also increase the etch rate of the poly(methylmethacrylate) block when exposed to oxygen plasma, as well as lower the Tg.

  • Patent number: 10961383
    Abstract: Novel block copolymers (“BCPs”) having non-random distributions of comonomers within at least one of the blocks and methods of using those BCPs in directed self-assembly (“DSA”) processes are provided. The non-random (e.g., gradient-creating) distributions can be customized in order to concentrate the desired comonomer properties in predetermined areas of the BCP. These BCPs can achieve perpendicular orientation with simple annealing and offer superior long-range ordering and lower defectivity when compared to prior art BCPs. These BCPs can be incorporated into compositions that simultaneously offer the benefits of high-? and rapid thermal-annealing kinetics while maintaining similar or improved guide process windows when compared to prior art BCPs.

  • Patent number: 10734239
    Abstract: Directed self-assembly (DSA) using block copolymers (BCPs) is emerging as a viable alternative to photolithography for creating features 10 nm and smaller. Block copolymers with balanced surface energy between the polymer blocks, tunable ?, and tunable glass transition temperatures (Tg) have been formulated. The block copolymers can achieve perpendicular orientation by simple thermal annealing due to the surface energy balance between the polymer blocks, which allows avoiding solvent annealing or top-coat. The ? value can be tuned up to achieve L0 as low as 12 nm for lamellar-structured BCPs and hole/pillar size as small as 6 nm for cylinder-structured BCPs. The Tg of the BCPs can also be tuned to lower than those of PS-b-PMMA standards. The enhanced polymer chain mobility resulting from the decreased Tg of the block copolymer may help with improving the kinetics of BCP self-assembly during the thermal annealing.
